“Unheimlich”

In a way Freud defines the “Latent dream thoughts” as a precursor to the “Manifested content material” in the dream. Freud says that the “task” of the dream interpreter is
Investigating the relations between the manifest content of dreams and the latent dream-thoughts, and of tracing out the processes by which the latter have been changed into the former.”(501)
That seems to imply that the meaning of the dream is floating around as something of an entity of its own: the manifested dream content is just the language of the dreamers unconscious. The Latent Dream thoughts are an a priori view of the inside of the dreamers psyche. The manifested Dream material is just the language that we use to read out the same old story, according to Freud. This leaves us with the impression that we can manipulate reality by infusing the Latent dream thoughts into a Manifested dream material directly before the author of the dream, dreams, we can predict the future.
